Feature Description
The UPF supports Cisco Ultra Traffic Optimization (CUTO) on Vector Packet Processing (VPP).
The Cisco Ultra Traffic Optimization is a RAN optimization technology that increases the subscriber connection speeds in congested cells and, as a result, increases the cell capacity significantly. The result is an optimized RAN, where Mobile Network Operators (MNOs) can deploy fewer cells, on an ongoing basis, and absorb more traffic growth while meeting network quality targets.
Large traffic flows, such as Adaptive Bit Rate (ABR) video, saturate radio resources and swamp the eNodeB scheduler. The Cisco Ultra Traffic Optimization employs machine learning algorithms to detect large traffic flows (such as video) in the network. It also optimizes the Delivery of those flows to mitigate the network congestion without changing the user quality (that is, video works the same for you). In other words, by employing software intelligence at the network core, Cisco Ultra Traffic Optimization mitigates the overwhelming impact the video has on the RAN.
The resulting benefits are seen in congested network sites. The Cisco Ultra Traffic Optimization:
-
Increases average user throughput.
-
Increases congested cell site capacity.
-
Reduces scheduler latency.
-
Maintains user quality of experience even when more users and more traffic share a cell.
-
Is measured directly by eNodeB performance counters (for example, average UE throughput, scheduler latency). These are the key performance indicators that are used for network capacity planning.
-
Provides permanent savings in RAN investment requirements.
-
Is integrated in the Cisco StarOS P-GW.
-
Requires no new hardware or cabling complexity - it can be turned on for a market in an hour.
-
Supports HTTP or HTTPS, and QUIC traffic.
